Chloe Goins, 24, claims Cosby drugged and assaulted her at the Playboy mansion in 2008, when she was a teenager.

The Los Angeles District Attorney is currently looking into the accusations, which surfaced in January (15), four months after the first of a group of alleged victims came forward with decades-old allegations of rape, drugging and inappropriate behaviour aimed at Cosby. More than 50 women have since come forward.

The comic's attorney, Martin Singer, has refuted the model's allegations, insisting he has proof to show that Cosby was in New York on the date that Goins claimed she was assaulted at the Playboy Mansion in California.

However, Goins is refusing to back down and she is now taking civil action against the funnyman.

In legal papers obtained by TMZ.com, Goins' lawyer outlines the growing list of accusations piling up against Cosby, and adds, "The nature of these activities establishes a history of a serial rapist that has been conducting these horrendous activities against women for over the last 40 years."

Goins is demanding more than $75,000 (£46,875) in damages for counts including mental anguish, loss of self-esteem and dignity.

The news of the lawsuit emerges as Cosby prepares to be deposed on 9 October (15) in relation to claims he acted inappropriately with Judy Huth during a party at the Playboy Mansion in California in 1974, when she was just 15.

It will be the first time he has spoken about a sexual assault allegation against him in a decade. He settled a previous case out of court in 2005 and has never been charged with any crime relating to the accusations.

Meanwhile, 27 of the women accusing Cosby of sexual assault have agreed to give on-camera interviews as part of an upcoming TV news special in America.

NBC News anchor Kate Snow will moderate the hour-long Dateline episode, which will air on Friday (09Oct15). It will feature model Beverly Johnson - the most high-profile of the 50-plus accusers, who have come forward with rape, drugging and disturbing sex tales about the comedian in the past year.

During the news special, the women will have the opportunity to respond to continued denials from Cosby's lawyers.

Gloria Allred, who is representing many of the accusers, will also take part in the programme. She has staged multiple press conferences with women who have accused Cosby of bad behaviour.
